Card Refund

When you purchase a new card you pay for it as consumer the owners Gautrain. Now the card expired with funds.now I'm being told i need to they will charge me an admin fee of R42 to refund my money back. Their card doesn't have or show any expiry date on and i didn't loose or damage the card .I had to buy new card to for my trip when I had a card loaded of cash and I couldn't use it. My expectations is to be refunded the full amount without any admin fee charged i don't understand this. Is reaping the consumers for using your services. The card is not lost or damaged if it has expired why must I pay for the new one and be charged to apply for my refund
